I know this is a very novice question, but if I go with 1.5 or 1.6 adj rockers is there anything I need to calculate into this before purchase?
I know these are novice questions but this is my first time with a V8 and want it done right, with the joy of doing it myself.
What are the pros and cons with 1.5 and/or 1.6 rockers?
What is the ideal setup when going roller?
Lifters: solid or hydraulic
Rockers: standard, standard adj, 1.5 adj, or 1.6 adj
Springs: How heavy?
Any other considerations?

1.6 rockers will give you a bit more lift, just want to make sure theres enough valve to pistion clerance, if you can use 1.6 go for it,
ideal set up as in what?
lifters you got to use what the cam is designed for, you nat use solid lifters on a hydraulic cam. hydraulic= good cams just have rpm limits, solid higher rpm limits more stable at higher rpms, but also you have to mantain them more often,
rockers adjustable you can set your own lash, roller rockers are all adjustable,
springs depends what the cam calls for, if you buy springs that have a inner spring its a good idea to take the inner spring out for cam break-in, also
67 gtx has a thread about oil and breaking in you should check that out also,
what engine are you building up?

Thank for the help! Good info!
I have a '78 440 that I am building. I want to put down over 500 hp.
My main goal is to beat or atleast keep up with my friend that has a 65 mustang putting down around 500. I need to show him that mopar is better.

If you are doing a fresh build,you need to put together a valve train package from the cam,lifters,pushrods,springs & retainers.I don't care for ISKy,had a terrible experience.I spent alot of time on the phone with COMP.Called 4 times and got 4 different cams reccomended,but they were all close to eachother.After doing your homework with a cam company,consult a builder that is familiar with MOPAR
